Search Engines have indexed the link with the port - What is the best way to prevent port indexing?

Hello colleagues! Decided to protest new service habr a difficult question, most likely, to experts on SEO. In general, there is a website, and there is also a port for testing new items - 8808. So the problem is that Yandex and Google indexed several pages like instead of and these pages are in the top your requests. Is there a way to somehow prohibit port indexation and preferably without a significant loss in the issue? Read more

Creating vlan

Need help. I have never encountered vlan before, but this is what needs to be done. In general, there is a linksys 4400n router, which sucks keeps the pptp connection with the provider.

XP as a router (resolved) / ssh-tunnel, VPN and iPhone

Recently I changed myself a stable, but relatively slow Internet via ADSL to faster and cheaper Internet via twisted pair (however, from the same provider). Prior to this, on all computers in the house, the Internet regularly distributed an ADSL modem / router to itself. Now I’m trying to set up an old laptop with XP. The Internet connects through a standard "high-speed connection, requesting a username and password." While on the laptop is 3proxy with http / socks, but I would like to get r... Read more

Ubuntu breaks connection with dsl.

I have a win7 and ubuntu 10.04 on my car. I decided to configure the Internet (finally!) Under Linux. Since I don’t understand much in Linux that it is configured using pppoeconf.

Knowing people tell me what’s wrong? Provider DOM.RU if it means something. (Omsk). Read more

3G USB modem - direct ip address

The task is to connect to the remote device using the http protocol. The device is connected to the Internet through a router with a USB modem. Resources: Dlink DIR412 router (or DIR320, there is one and the other), HUAWEI E160G modem (ZTE MF170), wireless ip camera. Current results: DynDNS does not work, because the Beeline releases everyone only through NAT. Dedicated ip address does not give to physicists, only to legal entities working on postpay. The megaphone seems to have ... Read more

Windows Port Forwarding

In Windows 7, you need to forward the port to the virtual machine that is running in it. Google issued a couple of programs - one loops and loads the processor, the other after restarting resets the settings, another one cannot read its configuration file, the other one asked to pay. Can someone tell me what solution? Details include: The computer (Windows 7 Pro) is accessible from the Internet, an internet connection via VPN, it runs Vmware Player with HostOnly network and Linux OS. It ru... Read more

Is there a universal free email to sms gateway in nature using Google Calendar API?

Greetings. I saw online services that allow you to send free SMS to mobile numbers using the Google Calendar API. But I could not find such an implementation that would allow sending a very small amount of SMS when a letter is received at a specific address, regardless of the operator, using, for example, Google Calendar. Have you met this by chance? P.S. I guess it would be easy to write for myself, but, alas, not a programmer, and there is no commercial interest - you just need... Read more
